thats not a tough question. the first one, apply a test voltage and measure the currents through all the branches. form a matrices and the equivalent resistance is the voltage/Current. will make use of inverse matrices. 1 Like |

SPLENDID25: Dude what? Look at the the original circuit... it's quite simple, no need to bring in the big guns like star to delta: - there's a 10 ohm in series with the rest of the network. - in this network, there's a 2ohm that goes directly to ground, in parallel with the rest of the network - in the smaller network, there's a 1ohm in series with a subset - in the subset there's a 2ohm in parallel with a 10ohm, both going to ground. From here it's the first week of circuits: reduce each network to its equivalent resistance, figure out the voltage drop as you go. How is this wrong? Intuitively, you know that 2//10 would be less than 2, and that the first series 10ohm will drop the majority of the voltage. 2 Likes

Re: Na Questions I No Fit Solve I Wan Dey Set: Usman Danfodio University Lecturer by nextstep(m): 11:48pm On Nov 19, 2021 |
SPLENDID25: Good, now keep rearranging and you'll likely arrive at my diagram: Bring in the 2ohm that's currently all the way to the right so it's next after the first 10ohm; then pull the point where the 1ohm, 2ohm, and 10ohm meet to the top right of that square; finally pull the bottom of that diagonal 2ohm to the right. You can almost visualize it. 1 Like |

Re: Na Questions I No Fit Solve I Wan Dey Set: Usman Danfodio University Lecturer by nextstep(m): 11:54pm On Nov 19, 2021 |
SPLENDID25: Glad you see it. Perhaps double check the math...? And you can do the same with the first circuit too. Starting from the right... I can't see the numbers too clearly, but you can visualize: ((((10 + 2) // 6) + 5) // 6) + 4) // 8 ) + 6 and so on then keep reducing till you get Req. The rest of the question is plug and chug. I knew some students in first year EE Ilorin who could finish this exam in under 5 minutes. What's truly sad is that all these brilliant minds have to deal with lousy lecturers who will bill them, or be frustrated into being cab drivers and akara fryers, are persecuted by police for being smart, and in some cases killed, and often just leave the country as soon as they can. Makes me shake my head to think of how Nigeria squanders its youth. |

nextstep:Total current=V/Rtotal= 10/11.142=0.897A 2ohm resistor between cd is parallel to 1ohm + 1.667ohms. Hence, current through 2ohm resistor is = (0.897/(2+1+1.667))*2.667=0.574A(using current division). Hence, voltage drop across 2ohm Vcd = 2*0.574=1.148V. Since current across Rab = 0.574, current flowing through the 1 ohm resistor will be 0.897-0.574=0.323A. Using current division again, Current flowing through the 10ohm resistor = (0.323/12)*2=0.054A. Hence, voltage drop across Vab= 10*0.054=0.54V. |

Bbqekpa:You people based everything on grades and you have 2-1 students from your place who paid their way to achieve that, can you compare them to a true second-class lower student in terms of merit? Another point is, the lecturer must have gotten wind of what students are saying behind his back, so he decided to use their own statement against them. He won't do this without the school knowing why he did that. |

Bbqekpa:he's just playing mind games with the students..,that statement alone will make lots of people fail because after solving and getting the correct answer at ease/in time, you will doubt your answer considering the statement the lecture wrote at the end of the question and some may want to solve it another way and finally fail. |
